USING THE UNIT SAFELY

008e

• Use only the attached power-supply cord.

..........................................................................................................

009

• Do not excessively twist or bend the power cord,

nor place heavy objects on it. Doing so can

damage the cord, producing severed elements and

short circuits. Damaged cords are fire and shock

hazards!

..........................................................................................................

010

• This unit, either alone or in combination with an

amplifier and headphones or speakers, may be

capable of producing sound levels that could

cause permanent hearing loss. Do not operate for

a long period of time at a high volume level, or at

a level that is uncomfortable. If you experience

any hearing loss or ringing in the ears, you should

immediately stop using the unit, and consult an

audiologist.

..........................................................................................................

011

• Do not allow any objects (e.g., flammable material,

coins, pins); or liquids of any kind (water, soft

drinks, etc.) to penetrate the unit.

..........................................................................................................

012b

• Immediately turn the power off, remove the AC

adaptor from the outlet, and request servicing by

your retailer, the nearest Roland Service Center, or

an authorized Roland distributor, as listed on the

“Information” page when:

• The AC adaptor, the power-supply cord, or the

plug has been damaged; or

• If smoke or unusual odor occurs

• Objects have fallen into, or liquid has been

spilled onto the unit; or

• The unit has been exposed to rain (or otherwise

has become wet); or

• The unit does not appear to operate normally or

exhibits a marked change in performance.

..........................................................................................................

013

• In households with small children, an adult

should provide supervision until the child is

capable of following all the rules essential for the

safe operation of the unit.

..........................................................................................................

014

• Protect the unit from strong impact.

(Do not drop it!)

..........................................................................................................

015

• Do not force the unit’s power-supply cord to share

an outlet with an unreasonable number of other

devices. Be especially careful when using

extension cords—the total power used by all

devices you have connected to the extension

cord’s outlet must never exceed the power rating

(watts/amperes) for the extension cord. Excessive

loads can cause the insulation on the cord to heat

up and eventually melt through.

..........................................................................................................

016

• Before using the unit in a foreign country, consult

with your retailer, the nearest Roland Service

Center, or an authorized Roland distributor, as

listed on the “Information” page.

flower vases) on this unit. Also, avoid the use of

insecticides, perfumes, alcohol, nail polish, spray

cans, etc., near the unit. Swiftly wipe away any

liquid that spills on the unit using a dry, soft cloth.

101b

• The unit and the AC adaptor should be located so

their location or position does not interfere with

their proper ventilation.

..........................................................................................................

102c

• Always grasp only the plug on the AC adaptor

cord when plugging into, or unplugging from, an

outlet or this unit.

..........................................................................................................

103b

• At regular intervals, you should unplug the AC

adaptor and clean it by using a dry cloth to wipe

all dust and other accumulations away from its

prongs. Also, disconnect the power plug from the

power outlet whenever the unit is to remain

unused for an extended period of time. Any

accumulation of dust between the power plug and

the power outlet can result in poor insulation and

lead to fire.

..........................................................................................................

104

• Try to prevent cords and cables from becoming

entangled. Also, all cords and cables should be

placed so they are out of the reach of children.

..........................................................................................................

IMPORTANT NOTES

291a

In addition to the items listed under “USING THE UNIT SAFELY” on page 2 and 3, please read and observe the following:

Power Supply

301

• Do not use this unit on the same power circuit with any

device that will generate line noise (such as an electric

motor or variable lighting system).

302

• The AC adaptor will begin to generate heat after long

hours of consecutive use. This is normal, and is not a

cause for concern.

307

• Before connecting this unit to other devices, turn off the

power to all units. This will help prevent malfunctions

and/or damage to speakers or other devices.

Placement

351

• Using the unit near power amplifiers (or other equipment

containing large power transformers) may induce hum.

To alleviate the problem, change the orientation of this

unit; or move it farther away from the source of inter-

ference.

352a

• This device may interfere with radio and television

reception. Do not use this device in the vicinity of such

receivers.

352b

• Noise may be produced if wireless communications

devices, such as cell phones, are operated in the vicinity of

this unit. Such noise could occur when receiving or initi-

ating a call, or while conversing. Should you experience

such problems, you should relocate such wireless devices

so they are at a greater distance from this unit, or switch

them off.

354b

• Do not expose the unit to direct sunlight, place it near

devices that radiate heat, leave it inside an enclosed

vehicle, or otherwise subject it to temperature extremes.

Also, do not allow lighting devices that normally are used

while their light source is very close to the unit (such as a

piano light), or powerful spotlights to shine upon the

same area of the unit for extended periods of time.

Excessive heat can deform or discolor the unit.

355b

• When moved from one location to another where the

temperature and/or humidity is very different, water

droplets (condensation) may form inside the unit. Damage

or malfunction may result if you attempt to use the unit in

this condition. Therefore, before using the unit, you must

allow it to stand for several hours, until the condensation

has completely evaporated.

356

• Do not allow rubber, vinyl, or similar materials to remain

on the unit for long periods of time. Such objects can

discolor or otherwise harmfully affect the finish.

359

• Do not paste stickers, decals, or the like to this instrument.

Peeling such matter off the instrument may damage the

exterior finish.

Maintenance

401b***

• To clean the unit, use a dry, soft cloth; or one that is

slightly dampened.

To remove stubborn dirt of plastic parts, use a cloth

impregnated with a mild, non-abrasive detergent. After-

wards, be sure to wipe the unit thoroughly with a soft, dry

cloth. Try to wipe the entire surface using an equal

amount of strength, moving the cloth along with the grain

of the wood. Rubbing too hard in the same area can

damage the finish.

402

• Never use benzine, thinners, alcohol or solvents of any

kind, to avoid the possibility of discoloration and/or

deformation.

Additional Precautions

551

• Please be aware that the contents of memory can be

irretrievably lost as a result of a malfunction, or the

improper operation of the unit. To protect yourself against

the risk of loosing important data, we recommend that

you periodically save a backup copy of important data

you have stored in the unit’s memory in another MIDI

device (e.g., a sequencer).

552

• Unfortunately, it may be impossible to restore the contents

of data that was stored in another MIDI device (e.g., a

sequencer) once it has been lost. Roland Corporation

assumes no liability concerning such loss of data.

553

• Use a reasonable amount of care when using the unit’s

buttons, sliders, or other controls; and when using its jacks

and connectors. Rough handling can lead to malfunctions.

556

• When connecting / disconnecting all cables, grasp the

connector itself—never pull on the cable. This way you

will avoid causing shorts, or damage to the cable’s

internal elements.

558a

• To avoid disturbing your neighbors, try to keep the unit’s

volume at reasonable levels. You may prefer to use

headphones, so you do not need to be concerned about

those around you (especially when it is late at night).

559a

• When you need to transport the unit, package it in the box

(including padding) that it came in, if possible. Otherwise,

you will need to use equivalent packaging materials.

561

• Use only the specified expression pedal (EV-7; sold

separately). By connecting any other expression pedals,

you risk causing malfunction and/or damage to the unit.

562

• Use a cable from Roland to make the connection. If using

some other make of connection cable, please note the

following precautions.

Main Features

Organ Features

Virtual Tonewheel Sound Generator

The VK-8M features a Virtual Tonewheel sound generator that perfectly simulates the sound-production

mechanism of traditional tone wheel organs. This rapid response is especially valuable when you use

characteristic organ performance techniques such as glissando. Since all parts — upper, lower, and pedal —

are completely polyphonic, notes aren’t cut off regardless of your performance technique.

Amp Modeling (COSM)

This technology analyzes the characteristics of the most popular amps and reproduces their warm, tube-like

sounds, as well as the unique sonic characteristics of their cabinets. You get four amp types, each with a

different sound, allowing you to perform using everything from clean to fat, overdriven sounds.

Rotary Sound

An effect algorithm using Roland’s COSM technology creates a faithful rotary speaker simulation that’s

essential for a great organ sound. Enjoy the realistic rotary sound simply by connecting a keyboard amp (such

as the KC series) or powered monitor (such as the DS series).

Integrated Controllers

Controllers such as the HARMONIC bars, [ROTARY SLOW/FAST] button, and OVERDRIVE knob have been

brought together with the sound module. No need to hassle with a bunch of connections–just connect your

own keyboard and start performing with authentic organ sounds.

Includes Input Jack

The unit includes an audio input jack, allowing you to input sounds from an external keyboard. Using the

input mix function, you can output the sounds of both the keyboard and the VK-8M without the need for a

separate mixer. The expression pedal function adds expression to the input sound, and the “Active

Expression” function further allows you to use the input sound as the Active Expression tone.

New Expression Pedal Function (Active Expression)

The expression pedal is an indispensable function for organ performances. When performing with the input

sound layered over the organ sound, the organ volume increases as you press the expression pedal, but when

Active Expression is used, the input sound volume makes a sudden jump to near maximum level.

Since the expression pedal can be used not only to change the volume, but the tone as well, it lets you enjoy

highly expressive performances.

Equipped with D Beam Controller

You can use the D Beam controller to control a total of six specialized effects with your performances, such as

switching the rotary speaker rotation speed and braking the tone wheel. is used to change The D Beam ON/

OFF button relies on new technology that allows for a range of different colors. Now push the envelope even

further in your stage performances.

Natural Wood Cabinet

The cabinet is built of wood, echoing the construction of traditional tone wheel organs. The VK-8M feature

beautifully finished natural wood that will gain luster with years of use.

Other Features

• MIDI connectors are provided on the rear panel, allowing you to connect a keyboard and pedal

keyboard and enjoy two-manual and pedal keyboard playing.

• User Registration memory lets you store 36 different panel settings.

How the VK-8M Works

■

About the Virtual Tonewheel Sound Generator

A traditional tone wheel organ produces the sound by 91 toothed wheels called “tone wheels.” Each tone

wheel produces a different pitch. A motor is used to rotate these tone wheels past electromagnetic coils, and

as the teeth of each wheel pass by the corresponding electromagnetic coil, an audio signal is generated. The

combination of harmonic bars and the notes that are pressed then select the audio signals that are output,

producing the sound of the organ.

The virtual tonewheel sound generator of the VK-8M uses digital technology to precisely re-create the sound-

production mechanism of a tone wheel organ. The 91 toothed wheels are constantly “rotating” digitally, and

are able to produce sound at any time. The sound produced by these virtual tonewheels is determined by the

combination of harmonic bars and the state of the notes played on the keyboard—exactly as on traditional

tone wheel organs.

■

How the Organ Sound are Created

Tone Wheels

Tone wheels rotate constantly, and will therefore “speak” the instant you play a note. The virtual tonewheel

sound generator of the VK-8M is also producing sound constantly, allowing very rapid response when you

play a note. This rapid response is especially valuable when you use characteristic organ performance

techniques such as glissando.

The organ sound consists of a fundamental and eight harmonics, and these are mixed according to the

combination of the harmonic bars. You can use the harmonic bars to modify the tone even while you play,

allowing a high degree of expressive flexibility.

Percussion

Tone wheel percussion is used when you want to add an attack to the notes you play, making the sound more

crisp. Relative to the pitch of the note you play, you can specify either the second (SECOND) or third (THIRD)

partial as the pitch of the percussion sound, and you can decrease the percussion volume (SOFT) or lengthen

its decay (SLOW).

The percussion on tone wheel organs is of a type called “single-trigger,” meaning that percussion was not

applied to all the notes that were played, but only to the note that was pressed first. If you release the

currently-played key(s), percussion will sound for the next-played note. If you play legato (with notes

smoothly connected), percussion will be applied only to the first note, and not to subsequent notes. If you play

staccato, percussion will be applied to all notes. If you play rapidly when using percussion, the percussion

circuit may not keep up with your playing, causing the percussion sound to become softer. However, the VK-

8M allows you to adjust the speed of recovery so that it will keep up even with rapid playing (p. 44). On a tone

wheel organ, the way in which percussion is applied is a very important element in enhancing the

expressiveness of the performance.

On tone wheel organs, the 1' harmonic bar was used to produce the percussion sound. This means that when

you add percussion, the sound of the 1' harmonic bar will no longer be heard. Also, percussion will be applied

only to the Upper Part.

On tone wheel organs, turning off percussion [SOFT] button would lower the volume of the organ, but the

VK-8M allows you to adjust it so the volume of the organ won’t change when percussion [SOFT] button is

switched on/off (p. 43).

Key Click

The first generations of traditional tone wheel organs produced a “blip” noise (separately from percussion)

when a note was pressed or released. Initially, this click noise was considered a problem, but blues and rock

musicians came to utilize it in their performances, and the key click became an indispensable part of the organ

sound in jazz as well.

On the VK-8M you can independently adjust the volume of the key click for key-on and key-off (p. 43).

How the VK-8M Works

Vibrato and Chorus

Traditional tone wheel organs provided a total of six different effects: three kinds of vibrato (V1, V2, V3) and

three kinds of chorus (C1, C2, C3).

Vibrato is an effect that cyclically modulates the pitch, and chorus is an effect that modulates the pitch to

produce spaciousness and depth.

Harmonic bars

The harmonic bars of a tone wheel organ are arranged in ascending order of pitch, from left to right.

Borrowing some inspiration from the pipes of a pipe organ, the bars are labeled in “feet,” with 8’ being the

fundamental.

There is one exception in the ordering of the harmonic bars, and that is the 5-1/3’ bar located second from the

left. According to the pitch order, this should be the third from the left, but since 5-1/3’ is an overtone of 16’,

and blends with the 16’ sound, it is placed beside the 16’ bar.

The harmonic bars are color-coded in three colors. The bars whose pitches are in octave relation to 8’ are white,

the bars that are not octave harmonics are black, and the lower pitch range is brown.

On tone wheel organs, the highest feet were repeated (“reused”) in the high keyboard range, and the lowest

feet were repeated in the low range. This is called “fold-back.”

If an organ had 109 tone wheels, all nine harmonics of the harmonic bars could be sounded by all 61 keys of

a tone wheel organ. However, if this were the case, the upper range would be unpleasantly screechy, and the

lower range would be excessively low and muddy-sounding.

For this reason, fold-back is used on the VK-8M to produce a well-balanced sound.

Amp Type (Rotary, Overdrive, Tone)

The VK-8M features four different amp types, reproducing everything from warm tube sound to the cabinets’

sonic characteristics.

Even if you are using a keyboard amp or monitor speakers, amp modeling gives you the sound of an actual

rotating speaker or a guitar amp sound, allowing you to enjoy performing with a wider variety of sounds.

What’s more, you can make settings for the rotary speaker volume, for the time used in switching between

the fast and slow rotation speeds, as well as the fast and slow rotation speeds themselves, and separate tweeter

and woofer settings for a greater sense of breadth in the sound.

Reverb

Reverb is an effect that adds reverberation to the sound. Reverb types ROOM, HALL, and CHURCH add the

reverberation of differently sized acoustical spaces. The SPRING reverb type simulates a reverb circuit that

used springs, and was often found on traditional organs.

The VK-8M lets you adjust the reverb time (p. 48). Also, by turning the [REVERB] knob you can adjust the

volume of the reverb (p. 34).

About the Memories

System memory

Settings that affect the entire VK-8M are referred to as “system memory.”

Registration memory

Settings that are stored independently for each registration number, such as harmonic bar and panel settings,

are called “registration memory.”

There are a total of 36 registration memories, and each of them can be edited.
